The defect
Motor Coach Industries (MCI) is recalling certain model year 2014-2019 J4500 and 2018-2019 J3500 motor coaches. The brake hoses may crack or otherwise fail resulting in an air leak. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
The risk
A leaking brake hose could cause a delay in the actuation time of the front brake, which would increase vehicle's stopping distance and increase the risk of a crash.
